The term source code management entails the processes and tools that developers use to track and control changes in software source code. This involves version control systems, which help teams collaborate more effectively on projects by managing revisions, branching, and merging code. Through proper source code management, developers can maintain a history of code changes, revert to previous versions when necessary, and ensure that the codebase remains organized and coherent. This practice is critical for maintaining code quality, especially in large or distributed teams.
